Fig. 5 is an enlarged side view of the front wheel brake 12. Fig. 6 is a front view of the front wheel brake arm 21 as viewed from the front of the vehicle body, and fig. 7 is an enlarged view of the lash adjustment mechanism. A front wheel brake arm 21 is provided on the front wheel brake disk 13 so as to be swingable via a swing shaft 18. A 1 st front wheel brake cable 22 and a 2 nd front wheel brake cable 23 adjacent to the 1 st front wheel brake cable 22 are coupled to the front wheel brake arm 21.
As described above, the right brake lever 26 is coupled to the 1 st front wheel brake cable 22, and the front wheel WF is braked by the operation of the right brake lever 26. On the other hand, a left brake lever 36 is connected to the 2 nd front brake cable 23 via an equalizer portion 34, and the front wheel WF and the rear wheel WR are braked by operation of the left brake lever 36.
The front fork 11 is a bottom link (bottom link) having a link arm 74 at the rear of the axle 72. The support portion 97 of the vehicle speed sensor cable 76 is provided to the front wheel brake disk 13, and the 1 st front wheel brake cable 22 and the 2 nd front wheel brake cable 23 are also supported by the support portion 97.
The front wheel brake arm 21 is biased in the brake release direction by a spring 75. The front end of the front wheel brake arm 21 is formed of two plate members arranged in parallel at a predetermined interval, and a play adjustment mechanism for the front wheel brake cable is provided between the two plate members. In order to ensure a larger brake operating force, the length of the front wheel brake arm 21 is set as long as possible, and the front wheel brake cables 22 and 23 are preferably connected at positions close to the front end of the front wheel brake arm 21.
Referring to fig. 6 and 7 in combination, a long hole penetrating through the two plate members in the vehicle width direction is provided at a lower portion of the front wheel brake arm 21. Specifically, a 2 nd hole 77b near the lower end and a 1 st hole 77a closer to the swing shaft 18 than the 2 nd hole 77b are formed.
A cylindrical 1 st coupling 82 is inserted through the 1 st hole 77a, and a 1 st adjusting bolt 83 for play adjustment is inserted through the 1 st coupling 82 and is disposed substantially horizontally. The rear end of the 1 st adjusting bolt 83 is coupled to the 1 st front wheel brake cable 22 at a position covered by the bellows cover 96. On the other hand, a 1 st adjusting nut 84 having a cylindrical body portion 84a is screwed to the front end portion of the 1 st adjusting bolt 83.
A cylindrical 2 nd coupling 78 is inserted into the 2 nd hole 77b, and a 2 nd adjusting bolt 79 for play adjustment is inserted through the 2 nd coupling 78 and is disposed substantially horizontally. The rear end of the 2 nd adjusting bolt 79 is coupled to the 2 nd front wheel brake cable 23 at a position covered by the bellows cover 95. On the other hand, a 2 nd adjusting nut 81 having a cylindrical body 81a is screwed to a tip end portion of the 2 nd adjusting bolt 79.
The 1 st hole 77a and the 2 nd hole 77b are each formed in an elongated hole shape elongated in the vehicle body longitudinal direction, and their longitudinal dimension is set to be larger than that of the 2 nd hole 77 b. Thus, when the brake-operation force is applied only to the 1 st front-wheel brake cable 22, the 2 nd coupling 78 slides within the 2 nd hole 77b, and the force applied to the 2 nd front-wheel brake cable 23 to which the brake-operation force is not applied can be released.
Such a structure is preferable in order to interlock the front and rear drum brakes with a simple structure, but when the vehicle travels in a state where the left brake lever 36 is not operated, there is a possibility that the 2 nd coupling 78 continuously abuts against the inner peripheral surface of the 2 nd hole 77b due to a play (gap) provided between the 2 nd coupling 78 and the 2 nd hole 77b, and a knocking sound is generated.
The interlock brake system of the present invention has a rattle preventing structure for preventing the rattle from being generated. Specifically, a columnar projection 78a having a groove 78b is provided on the inside in the vehicle width direction of the 2 nd coupling 78 (the right side in the vehicle width direction in the present embodiment), and a columnar 1 st projection 82a having a groove 82b is provided on the inside in the vehicle width direction of the 1 st coupling 82.
Fig. 8 is a perspective view of the connecting portion between the front wheel brake arm 21 and the 1 st and 2 nd coupling members 82, 78 as viewed from the inside in the vehicle width direction. Coil springs 83a and 79a are wound around outer peripheral portions of the 1 st and 2 nd adjusting bolts 83 and 79, and the coil springs 83a and 79a are used to return the 1 st and 2 nd adjusting bolts 83 and 79 to initial positions when the brake levers 26 and 36 are not operated. In the present embodiment, the following knocking sound prevention structure is provided: the 1 st boss 82a and the 2 nd boss 78a are caused to protrude from the vehicle width direction inner sides of the 1 st and 2 nd coupling members 82, 78, respectively, and the 1 st boss 82a and the 2 nd boss 78a are drawn close to each other by a spring member 100 as an urging unit. Thereby, the cylindrical side surface of the 2 nd coupling 78 is pressed against the upper side surface of the 2 nd hole 77b, and the 2 nd coupling 78 can be prevented from jumping under vibration.
In the present embodiment, in order to pull the 1 st link 82 and the 2 nd link 78 toward each other, the direction in which the 2 nd link 78 is pulled toward is along the length direction of the front wheel brake arm 21. This direction is preferably substantially perpendicular to the longitudinal direction of the 2 nd hole 77b, that is, the moving direction of the 2 nd coupling 78, so that the original operation of swinging the front wheel brake arm 21 by the 2 nd coupling 78 is not hindered.
Further, since the spring member 100 is positioned on the vehicle width direction inner side of the front wheel brake arm 21 and is disposed between the 2 nd projection 78a and the 1 st projection 82a, the spring member 100 can be protected from flying stones and external forces.
